To all whom t may concern:

Be it known that I, JOHN M. ABRAMS, a citizen of the United States,residing at Bentley Manor, in the county of Richmond and State of. NewYork, have invented certain new and useful lmprovements in Tires, ofwhich the following is a specilication.

My invention relates to tires of that class known as 'cushion tires.

It has 'for its' object to provide a tire which will possesatheadvantages of a pneumatic tire in that 'iti is elastic and resilient,but which will avoid the disadvantages of the pneumatic tire in that itselasticity or resiliency are in no wise affected by puncture.

It has for a further object to provide a tire which is more durable,simpler in construction and more easily applied and removed than apneumatic tire or other cushion tires now in use.

It has for a further object to provide a tire having a spiral metalspring therein to augment the elasticity and resiliency of the outercasing.

lt has for a further object to provide a tire of the characterdescribed, having a leather tube between the outer casing and spring toprevent injury to the outer casing by contact of t-he spring therewithand provided with a spiral groove which receives the spring and holds itin place and spaces its convolutions.

lt has t'or a further object to provide a a tire of the characterdescribed, having the outer casing split longitudinally, the leathertube split longitudinally and a longitudinal supporting strip locatedbetween the outer casing and tube and extending across the space betweenthe longitudinal edges of the casing and tube and is provided with alongitudinal rib extending into the space between the longitudinal edgesof the casing.

In the drawings: Figure 1, is a fragmen tary sectional View showing mytire applied to a wheel.` Fig. 2, a transverse sectional view showing mytire`applied yto a wheel.

Referring to the drawings illustrating my invention, in which likereference characters designate corresponding parts, 1` designates therim of a wheel, 2 the spokes and 3 the shoe of a tire, consisting of anouter casing split longitudinally to form two longitudinal.

edges and provided with lateral longitudinal flanges 4 and 5. The tireis secured to the rim, on oneside, by means of a ring 6 which engagesthe flange 4 of the outer casing and the Hangs 7 of th.n rim and securedon the' other side by means of a ring 8 which engages the flange 5 ofthe outer casing and a ring '9 which engages the ring'8 and the flange10 of the rim. The outer casing 34 is provided with recesses 11 in itsinterior: along its longitudinal edges for the purpose to be hereinaftermentioned.

A leather tube 12 is located in thelouter casing and is provided with aspiral groove 13 1n its mner circumference in which seated a metalspiral. spring 14. 'Ihisftube- 12, on account of separating the metalspring 14 from the rubber outer casing 3, prevents.'

wear and other injuries tothe outer casing:

which would result from the metalspring` contacting therewith, onaccount of being made of leather forms a tough flexible surface for themetal spring to bear againstand on account of being split lo ltudinallyis easily'placed on or remove from the spring. The A groove 13 in thetube 12 retains the spring 14 therein and Spaces itseonvolutionssothat,when pressureisplaced on thespring, its convolutionswill not beforced together or apart and lessen its spring action.

A longitudinal supporting strip 15, preferably of leather, is locatedbetween the tube 12 and the outer casing and extends across the spacebetween the longitudinal edges of the casing and tube into the recesses1l Aand is provided with a longitudinal rib 16 which extends into thespace between the longitudinal edges of the casing and bears on the rim1 of the wheel. The strip 15 is made ofsuch length that when its rib 16is in vthe center.

of the space between the longitudinal edges of the casing 3, its endswill extend short of the ends of the y slots 11 thus, when it is idesired to remove the tire from or secure it on the rim 1, the strip 15and casing 3 can be forced laterally in the proper direction to allowthe ring 9 to be removed or inserted as required. This strip 15 onaccount myself to the details of constructioi'i and ary rangement asherein described and illus-A trated, as itis manifest that variationsand modifications may be made in the features of i construct] on andarrangement 1n the adaptation of the device to various conditions ofusewithout departing from the 'spirit and scope,of my invention andlmprovements.

therefore reserve the right to all such varia-v tions and modificationsas properly fall within the scope of my invention' and the terms of thefollowing claims. "i I claim: y

1. In a tire, an. outer casing split longitudinally, a leather tube insaid easing having a spiral groove and a spiral spring seated in saidgroover and its eonvolutions being spaced thereby, substantially asdescribed.

2. ln a tire, an outer* casing split longitudi'nally, a leather tubeinsaid casing split longitudinally and having a spiral groove and a-spiralspring seated in said groove and its convolutions being spaced thereby,substantially as described.

3. ln a tire, an outer casing 'split longitudinally and having recessesalong its longitudinal edges, a tube in said casing splitlongitudinally, a spring in said tube, means retaining said spring insaid tube and spacing its convolutions and a longitudinal supportingstrip located between said casing and tube and extending across thespace between thc longitudinal edges of said easing and tube into therecesses in said casing, substantially as described.

4. In a. tire, an outer easing split longitudinally, a tube in saideasing split longitudinally7 a spring in said tube, means retaining saidspring in said tube and spacing its convolutions and a longitudinalsupporting strip located between said easing and tube and extendingacross the space between the longitudinal edges of said casing andprovided with a longitudinal rib extending into the vspace between thelongitudinal edges of said easing and adapted to contact with the rim ofa Wheel, substantially as described.

In testimony whereof, I have signed my name in the presence of twosubscribing witnesses.

JOHN M. ABRAMS.
